5,10,15,20,25 set of rule form?

Answer:

{x|x is one of the first five multiple of 5}

Explanation:

Descriptive Method

{first five multiples of 5}

Roster Form

{5, 10, 15, 20, 25}

Rule Form

{x|x is one of the first five multiples of 5}

read as: "the set of all x, such that x is one of the first five multiples of 5""

first five multiples of 5" was written instead of "multiples of 5" because the elements on the set ended on 25. If it had three dots "..." which means "and so on", then the multiples keeps on going but since it stopped at 25, therefore only 5 multiples are present in the set.
